It shouldn't. Most production vehicles built from 1990 to date, have a "knock" sensor which accommodates different octane levels.

Does high octane gas increase mileage?

Not unless the engine using it was specifically designed for it. Gas mileage takes many things into consideration, and if a car is designed to use standard octane gas, the use of high octane gas will not increase the car's mileage - it is just a way of figuratively blowing dollar bills out of the tailpipe.

If a car has been given a certain type of gas for a long time would it hurt to start giving it different type of gas?

It would only hurt if the car required 89 octane or 92 octane and you went to a lesser octane. Those cars are engineered to run on a higher octane. A car engineered for the lower 87 octane might actually see some performance improvement by going to a higher octane once or twice, because the higher octane will help to clean the injectors a "little". Not much though. Over all there is no real significance to using the higher octane. The higher the octane level, the "richer" or "heavier" the fuel is. So if the car is not manufactured for the higher octane, you will eventually cause carbon build up at a faster rate than normal.
